 __**Quadratic Formula and Imaginary Numbers**__

Quadratic Formula

math x = \frac math

The quadratic formula can always be used to solve equation in the form of

math \[ ax^2 + bx + c = 0 \] math

Where, "a " is always the coefficient of math \[ x^2 \] math

"b " is always the coefficient of x. "c ' is always a constant.

The quadratic formula and Imaginary Numbers are both connected. They are connected because the quadratic formulas have a square, if the square root is of a negative number; you’re going to end up with an imaginary number.

An example:

math \[ 2x^2 + 3x + 4 = 0 \] math 
 * Remember** that a= 2, b=3, and c=4

Plug in the numbers in to the Quadratic Formula (shown above):

math x = \frac math

Simplify:

math x = \frac math

Simplify:

math x = \frac math

Then:

math x = \frac math
